Preoperative symptoms, visual analog scale (VAS) pain scores, perioperative complications, and the need for subsequent revision surgery were recorded. Each patient was then contacted via telephone to determine current symptoms and VAS score. Follow-up was available for 22 of 24 patients, and the follow-up period ranged from 1 to 22 months. Clinical outcome was gauged by comparing VAS scores prior to surgery and at the time of telephone interview.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total of 24 consecutive patients underwent lumbar arthrodesis surgery in which the hybrid system was used for adjacent-level dynamic stabilization. The mean preoperative VAS score was 8.8, whereas the mean postoperative VAS score was 5.3. There were five perioperative complications that included 2 durotomies and 2 wound infections. In addition, 1 patient had a symptomatic medially placed pedicle screw that required revision. These complications were not thought to be specific to the DTO system itself. In 3 patients treatment failed, with treatment failure being defined as persistent preoperative symptoms requiring reoperation.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The DTO system represents a novel hybrid dynamic stabilization and fusion construct. The technique holds promise as an alternative to multilevel lumbar arthrodesis while potentially decreasing the risk of adjacent-segment disease following lumbar arthrodesis. The technology is still in its infancy and therefore follow-up, when available, remains short. The authors report their preliminary experience using a hybrid system in 24 patients, along with short-interval clinical and radiographic follow-up.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2010.3.focus1055","type":"journal-article","created":{"date-parts":[[2011,2,23]],"date-time":"2011-02-23T11:43:05Z","timestamp":1298461385000},"page":"E2","source":"Crossref","is-referenced-by-count":38,"title":["The use of a hybrid dynamic stabilization and fusion system in the lumbar spine: preliminary experience"],"prefix":"10.3171","volume":"28","author":[{"given":"Matthew B.","family":"Maserati","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew J.","family":"Tormenti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David M.","family":"Panczykowski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher M.","family":"Bonfield","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter C.","family":"Gerszten","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-0280002","series-title":"J Spinal Disord Tech","doi-asserted-by":"publisher","first-page":"376","DOI":"10.1097\/BSD.0b013e31817c6489","article-title":"Posterior pedicle fixation-based dynamic stabilization devices for the treatment of degenerative diseases of the lumbar spine","volume":"22","author":"Bono","year":"2009"},{"key":"b2-0280002","series-title":"Spine","doi-asserted-by":"publisher","first-page":"455","DOI":"10.1097\/01.BRS.0000090825.94611.28","article-title":"Critical analysis of trends in fusion for degenerative disc disease over the past 20 years: influence of technique on fusion rate and clinical outcome","volume":"29","author":"Bono","year":"2004"},{"key":"b3-0280002","series-title":"Spine","doi-asserted-by":"publisher","first-page":"2253","DOI":"10.1097\/BRS.0b013e31814b2d8e","article-title":"Adjacent segment disease following lumbar\/thoracolumbar fusion with pedicle screw instrumentation: a minimum 5-year follow-up","volume":"32","author":"Cheh","year":"2007"},{"key":"b4-0280002","series-title":"Arch Orthop Trauma Surg","doi-asserted-by":"publisher","first-page":"39","DOI":"10.1007\/s004020100314","article-title":"Adjacent segment degeneration after lumbar spinal posterolateral fusion with instrumentation in elderly patients","volume":"122","author":"Chou","year":"2002"},{"key":"b5-0280002","series-title":"Spine","doi-asserted-by":"publisher","first-page":"574","DOI":"10.1097\/00007632-198409000-00007","article-title":"Lumbosacral spinal fusion.
